end for the body and at the other end being formed with'tab projections particularly constructed in'outline and scored for folding on definite lines in order to provide at the closed end of, the body a. materially, reinforced wall which will-be completely solid, when the sections are folded, in a manner to prevent any possible leakage from the interior of the-body.

,A further object of the invention is the provision of aninner receptacle which has a drawerlike cooperation with the body and which is constructed of a single blank which, at one end, provides a double interlocked thickness to prevent the possibility of material supported in this inner: receptacle and whichis liable to become softened'duringtransportation or storage from soaking into or softening the end of the receptacle with consequent liability of breaking down the o endwall of the receptacle and preventing proper 3 withdrawal offjthe material when the receptacle is withdrawn. a

The invention is illustrated: in the accompanying-drawings inwhich:

'With particular reference to Figures 1, 2, 3, r

and 4, which illustrate the box form, l; indicates the blank'which may be formed of cardboardor other appropriate'material and-which may be made up of sections 2, 3, 4, 5, and 6 marked for folding on;scored lines ,1, 8, 9, and Id into a rectangular form body, the section 6 of which is the uniting section, as is conventional.

At the end of each of the sections 2, 3, 4, and 5 there is provided an extension in the form .of a wall-reinforcing flap, such flaps being indicated at ll, l2, l3, and Id. These wall reinforcing flaps are of the full width of the sections to which they are connected and of a length sornewhat less than half the width of the sections. These wall reinforcingflaps are divided one from the other on the lines of fold l, 8, 9, and H], as indicated at E5, and are scored for folding on lines transverse the sections, with such lines of fold indicated at l6. 7 h 1 Each reinforcing flap is provided with folding flaps designed to be interfolded to form the end of the box-like body. The main such folding flap is indicated at ll and extends beyond thereinforcing flap it! with an'indicated line of fold I8 between them. The folding flap i1 is of the full width of the aligned box section 3 and has a length corresponding to its width, that is a dimension corresponding to the interior dimension of the box. The folding flap I! has wings I9 and 20, foldable with respect to the main portion on lines of fold 2i, which lines of fold are extensions, that is in alignment with the lines of fold 1 and 8. V The wings 9 extend throughout the full, length of the folding flap ll, being cut awayjat 22 and thus divided from identical folding fiaps23 and 24 which are aligned with the sections 2 and .4, of the full width of the reinforcing flaps II and I3 to which they are connected by lines of fold.

25 and which, beyond the reinforcing flaps, are

convergent in correspondence with the line of fold 2|.

A final folding flap 26 having a dimension corresponding to the interior dimensions of the box is arranged in line with the section 5 and connected by a line of fold 2! with the reinforcing flap l4, the folding flap 26 being otherwise free of connection with any of the parts and being slightly reduced in width to accommodate the thickness of the wall reinforcing flaps when folded, as will later appear.

The box shown in Figure 1 is made up as follows: The sections 2, 3, 4, and 5'are folded on the lines 1, 8, and 9 into a rectangular formation, the extension 6 being folded, on the line and adhesively secured to the inner surface of the section 2 to secure the sections in box-forming relation. The folding flap I1 is first folded at the end of the box. This fold is illustrated in Figure 2. The fold is made by first folding the reinforcing flap l2 inwardly against the section 3. The flap I7 is disposed transverse the interior of the box and the wings I9 and 29 folded against the flaps 2 and 4. The second folds in completing the end of the box are illustrated in Figure 3. Here the folding flaps 23 and 24 are folded inwardly, the reinforcing'fiap sections H and I3 being folded against the sides of the box and the portions 23 and 24 being folded to rest upon the flap H. The final fold is indicated in Figure 4, wherein the final folding flap 26 is folded inwardly upon the flaps 23 and 24, the reinforcing flap I4 resting against the reinforcing flap l3. The folded end of the box is then complete and it will be noted that by the various folds, the end of the boxis completely sealed against leakage and the actual bottom of thebox is arranged inwardly of the end of the box proper and of triplicate thickness. 1

In Figures 5 and 6 there is shown the interior drawer or carrier for the form of blank shown in Figure 1. This interior carrier or drawer is also made of a single blank 28 comprising a section 29 which has a width equal to the width of the formed box body and a length equal to the distance from the free edge of the box body to the folding flap H which forms the front face of the rear wall of the box body. On the forward end the section 29 is provided with an end section 30 commensurate with the interior dimensions of the box and foldable with respect to the section 29 on a marked line 3|. The end section 30 is provided with a triangular tab 32 foldable with respect to the end section on a line 33 and the end of the end section 38 is formed with a finger tab'34 folding on the line 33 and otherwise cut out from. the end section 39.

The opposite end of the section 29 is formed with an end wall 35 corresponding to the'end section 30 and foldable with respect to the section 29 on a line of fold 36.

Laterally of the end section 29 is a reinforcing section 31 corresponding in size and shape to the section 35 and a triangular section 49 extends from the end of the free outer edge of the reinforcing section 31 to the adjacent edge of the section 29, the triangular section 40 being foldable with respect to the section 29 on a line of fold 4| which is continued as a line of division between thesections 35 and 31, and the triangular section 4|! being foldable with respect to the section 31 on a line of fold 42 forming a continuation of the line of fold 36. The section 3'. is. cut out to form a securing tab 43 and the section 38 is formed With an incision 44 to receive the tab 43.

In making up the drawer or inner container, the section 35 is first folded upwardly at right angles to the section 29 on the line of fold 36. The sections. 31 and 40 are folded upwardly on the line of fold 4| and the section 31 folded at right angles to'the triangular section and placed immediately in rear of the section 35, the securing tab 43 being passed through the slot 44. The rear Wall is thus reinforced by the section 31 which is prevented from separation by the triangular section 40 and by the securing tab connection. The triangular section 49 forms a partial side for the container, the section 29 being otherwise without side walls. The end section 3|! is turned up at right angles to the section 29 on the line of fold 4| and the triangular tab turned inwardly and inserted beneath the top wall of the box when 'the drawer is pushed in to its limit, the tab 34 forming a finger-piece for convenient withdrawal of the drawer.

The box package form in Figures 1 to 6 is of rectangular form and it is contemplated to construct the same of triangular form in cross section, as may be desirable in some instances, while maintaining the advantages of the rectangular form with respect to the sealing of one end of the box body and its reinforcementat the sealed end. The triangular form of the body of the box is illustrated in Figures 7 to 10, inclusive, while that of the drawer or inner container for such triangular box body is shown in Figures 11 and 12.

v Figure 7 illustrates the blank used in making up the triangular form of box body. Such blank, indicated generally at 45, comprises'sections 46,

41, and 48 and a securing section 49, the blank being scored or otherwise formed to indicate lines of fold at 50, 5|, and 52. Arrangedin aligncorresponding to the width of the main section and is foldable with respect to the Wall reinforcing flap 54 on a line of fold 59. The folding flap 58 is triangular in form, corresponding in shape and size to the interior of the box body when formed, and is further provided with Wings 60 on opposite edges extending throughout the full length'of such edges and foldable with respect thereto on lines of fold 6|.' The wings extend from the apex of the main folding'flap 58 and. have at theapex, ends 62 which are at right angles to the lines of fold 6|, the opposite ends of the wings being on more acute angles with the lines of fold, as indicated at 62; This formation provides for avoiding conflict with other folds, as willbe evident from a description of the assemblage. End folding fiaps' 63 of triangular form are arranged immediately beyond the wall reinforcing flaps 53 and 55 and foldable with respect thereto on lines of fold 64. The base of the folding flaps 63 are of the full width of the sections with which they are aligned and, of course, have a triangular form corresponding in size and shapeto the box body when completed.

The triangular form box body is formed in the same manner as the rectangular box body in that the'sections' 41, 48, and 49 are'folded into triangular outline on the lines of fold'5fl and 5|.

The section 69 is folded on the line 52 and secured inwardly of the section 48 to maintain the conthe wall reinforcing fiap 54 and triangular. folding flap 58 arefolded inwardly, the triangular flap 58 being folded at right angles to the wall reinforcing fiap 54, the wings 611 being folded upwardly at right angles to the folding flap 5%. -When finally positioned, the reinforcing flap 54 rests against the inner surface of the section H, the folding flap 58 fits within and fills the in- .terior of the formed box body at right angles to its sections or walls and the wings 60 bear against the remaining sections 46 and 48 of the box body. The second fold is illustrated in Figure 9 where the folding flap 63 and wall reinforcing fiap 55 are turned inwardly, the ,wall reinforcing flap cooperating with the inner surface of the wall of the section 48 and the folding flap 63 overlying and resting upon the previously disposed folding flap 58. The final fold is shown in Figure 10 wherein the folding flap 63 and wall reinforcing flap 53 are folded inwardly against the section 46 with the wall reinforcing flap bearing against the inner surface of the section 46 and the section 53 bearing upon the previously applied folding flap 63. Y

It will thus be noted that each wall or main section of the box body is reinforced or of double thickness at one end and that inwardly of the reinforced portion of the wall, a bottom for the box is formed which is in triplicate and so arranged and disposed as to completely seal this end of the box body against leakage.

The inner container or drawer for use with the box body of triangular shape is illustrated in Figures 11 and 12. The blank, shown at 65 in Figure 11, has a main section 66 having a dimension to fit snugly within the box body of triangular form between the closed bottom and the free edge. At that end of the section 66 which cooperates with the free end of the box body, there is provided a triangular end wall 6! foldable with respect to the section 66 on fold line 68, with such end wall of triangular shape to correspond in size and shape to the interior of the box body and further formed on one triangular edge with a wing 69 having a curved free edge and projecting below the apex of the end wall 61 in a rounded form at it, the opposite triangular edge of the end wall having a wing H to fit within the interior of the free end of the box body to hold the end wall in closing position.

The opposite end of the section 65 is provided with a triangular folding flap T2 foldable with respect to the section 66 on fold line l3 and with a laterally disposed additional folding flap M connected with the section 66 by a substantially triangular side wall section 15 having a curved free edge. The side wall section 15 is foldable with respect to the main section 56 on fold line 16 while the laterally disposed folding fiap i4 is foldable with respect to the side wall 15 on a fold line "H 3 at right angles to the section 66. iliary'folding flap M and side wall 15 are folded upwardly with respect to section 66 on the line 16 and the auxiliary folding fiap I4 is then folded on line H in rear of the folding fiap 12 and the tongue 78 passed through the incision l9, as indicated in Figure 12. Of course, the end wall 61 is folded upwardly and the wing H inwardly, the latter on fold line 80 to fit the open end of the box body when the drawer is in place, the wing 69 being folded outwardly on fold line 8| to provide a finger-piece for withdrawing and handling the drawer.

In both forms of the box construction, it will be noted that the closed end of the box body is of maximum strength for the material used in that it is of triplicate layers and that each of the flaps making up a layer has an integral connection with one of the walls of the box body. and a section which folds down in contact with that wall not only to reinforce it but to seal the juncture against leakage. Thus, the closed end of the box, entirely without the necessity of any adhesive or The 21119.

other extraneous connector, is locked in proper relation to the walls of the box body by the super-imposed flaps and each side or wall of the box body is sealed by the arrangement of the bottom flaps against possible leakage beyond the bottom. The drawer of each form provides a side wall which tends to position and retain the material to some extent and a double thickness end wall to bear against the bottom, with the juncture of the side wall and end wall completely sealed against leakage. Thus, any materials in the drawer or inner container which tend to become soft in storage or when not in use, cannot possibly leak beyond the end wall of the inner container and will be withdrawn when the inner container or drawer is withdrawn.

Of course, either of the forms of boxes herein described may be made of any appropriate materials and obviously of any size longitudinally or transversely. The rectangular box body of the preferred form is made up of four walls and though shown of greater length and diameter, may obviously be of any relative lengths and diameters with particular regard to the materials to be stored in the package.

It is to be understood also that the various folding flaps are of such relative dimensions that each will be accommodated, in the regular order of folding, within the surface already formed by the previously folded flaps to secure a more or less frictional holding. This will dispense with the necessity of any adhesive though, if in a par.- ticular package, it is deemed advisable from the standpoint of extreme caution, adhesive may be employed in securing the parts in fixed relation.

What is claimed to be new is:

1. A box body made up of main sections foldable to present a hollow box completely open at one end, the opposite end of each of the main sections of the box having projecting tabs, each connected to its main section by a wall reinforcing flap foldable on predetermined lines with respect to the flap and tothe main section, the tabs of one pair of opposing main sections being of the full interior area of the box, the tabs of the remaining main sections being of approximately one-half the interior area of the box, one of the full area tabs having side flaps foldable with respect to the tab and commensurate in width with with the Wall reinforcing flaps, the tab with the side flaps being initially folded to arrange the flap in position to close'the interior of the box,

with the wall reinforcing 'fiap and the side flaps of this tab bearing against three separate main sections of the box; the short length tabs being then folded to cause their wall reinforcing flaps to overlie the side flaps of the first folded tab, with the short length tabs together forming a single layer resting upon the first folded tab, the final full area tab being then folded to cause its wall reinforcing flap to cooperate with the main section with which it is connected and to overlie and bear upon both of the short length tabs to complete the bottom closure of the box.

2. A box having a triplicate bottom formed of tabs integral with the respective walls of the box, with each tab having a wall reinforcing means sealing the bottom of the box against leakage, the opposite end of the box being open, and a drawer fitted within the box and comprising a main section corresponding in width to that of one of the walls of the box, an end wall of double thickness integral with the drawer, and a side wall extending from the end wall for a distance materially less than one-half the length of the main section,

the remaining'side edges of the main section being without projection.

3. A box having a triplicate bottom formed of tabs integral with the respective walls of the box, with each tab having a wall reinforcing means sealing the bottom of the box against leakage, the opposite end of the box being open, and a drawer fitted within the box and comprising a main sec tion corresponding in width to that of one of the walls of the box, an end wall of double thickness integral with the drawer, and a side wall extending from the end wall for a distance materially less than one-half the length of the main section, the remaining side edges of the main section being without projection, the end of the main section opposite the end wall being provided with a flap serving to close the open end ofthe box when the drawer is in place and to provide a pulling flap for the drawer when the latter is to be removed.
